Appendix 2, 5/1/2005
open circuit, step in voltage test results. Recordings of the generator terminal voltage and generator field voltage magnitudes must be provided together with any calibration data necessary to equate the recordings with actual voltages. In situations where it is impractical to measure the generator field voltage (e.g. brushless excitation systems) alternate quantities with equivalent response characteristics can be provided. An estimate of the generator’s field winding temperature during this test must be provided.
